converting date from DD-MON-YYYY to YYYYMM format

[Anon]

Trying to convert a date in DD-MON-YYYY format to YYYYMM format, eg 30-SEP-2001 to 200109.
Tried using the following code but it does not work :

$var_date = strtotime ("30-SEP-2001");
echo (date ("Ym",$var_date));

Any advice.
Thanks.

I do it like with strings:

$today=date('d.m.Y');
$date=$today;
//convert date from 'dd.mm.yyyy' to '1999-11-31' format
if($date){
$arr_date=explode('.', $date);
$mysql_date=$arr_date[2].'-'.$arr_date[1].'-'.$arr_date[0];
}else $mysql_date='';

Hope, that's what you need...
